Stein Seals

Since 1955, Stein Seal Company has been a leading provider of custom designed seals and precision components for use in a wide variety of aerospace, marine and industrial applications. Starting in a rented space with five employees, Stein Seal steadily grew into the recognized industry leader we are today. In 1987, we moved into our own modern manufacturing plant, and with building additions over the years, now have over 100,000 square feet in this highly specialized facility.
